Description

Technical Field

[0001] The utility model relates to the technical field of agricultural planting, in particular to a fertilizing device used for seed planting. Background Art

[0002] Agriculture is an important industry in the national economy. In agricultural planting, planters will use fertilizer devices to fertilize the soil to make the plants thrive. The existing agricultural planting fertilizer devices are easy to operate and have ideal fertilization efficiency. They are convenient for people to use when fertilizing plants, but there are still many inconveniences.

[0003] After searching, it is found that a Chinese patent document discloses a fertilizing device for agricultural planting [application number: CN202221739013.7]. This fertilizing device for agricultural planting includes a connecting plate, a mounting hole is provided on the top of the connecting plate, a fertilizer box is fixedly connected inside the mounting hole, a crushing box is fixedly connected to the top of the fertilizer box, and a lifting hole is provided on the middle of the bottom wall of the crushing box; when in use, the fertilizer needs to be crushed with a crushing knife to speed up the speed at which the fertilizer is absorbed by the soil, and the crushed fertilizer will enter the interior of the fertilizer box through the leakage hole, and then fall on the soil from the discharge port at the bottom of the fertilizer box.

[0004] When the device disclosed in the patent is used, the crushing knife can crush the fertilizer so that it can be quickly decomposed into the soil, and the discharge port can also be unblocked by the electric push rod. However, when the discharge port is unblocked, the crushing knife will be moved together, and the lifting motor and the electric push rod need to cooperate with each other. Not only is it cumbersome to open and close the lifting motor and the electric push rod, but it also increases the production cost of the device, resulting in reduced applicability of the device.

[0005] At the same time, the device can filter the crushed fertilizer through the leakage hole to prevent the un-crushed fertilizer from being discharged from the discharge port. However, during use, the un-crushed fertilizer may be blocked on the surface of the leakage hole, resulting in the crushed fertilizer being unable to be discharged, which not only affects the normal fertilization of the device, but also reduces the efficiency of fertilization.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-5As shown, a fertilizing device for seed planting includes a storage mechanism 1, which can store fertilizers and tools. A crushing box 2 is arranged on one side of the storage mechanism 1. A support frame 3 is fixedly connected to the top of the crushing box 2. The support frame 3 is designed as an L-shaped structure. A stepper motor 4 is bolted to one side of the support frame 3. A worm 5 is fixedly connected to the output shaft of the stepper motor 4. A linkage mechanism 6 is installed at the bottom of the worm 5. With the cooperation of the linkage mechanism 6, the power of the stepper motor 4 can be transmitted, so as to facilitate the subsequent crushing of the fertilizer. A stirring rod 7 is arranged at the bottom of the linkage mechanism 6. The other end of the stirring rod 7 penetrates into the inner cavity of the crushing box 2 and is movably connected to the inner wall of the penetration point. Crushing blades 8 are fixedly connected at two places on the surface of the stirring rod 7. Under the action of the crushing blade 8, the fertilizer inside the crushing box 2 can be crushed, thereby reducing the volume of the fertilizer, thereby increasing the speed at which the fertilizer is absorbed by the soil. The inner cavity of the support frame 3 is installed with a moving mechanism 9, and the moving mechanism 9 is used in conjunction with the linkage mechanism 6. Under the action of the moving mechanism 9, the crushing blade 8 can move up and down when crushing the fertilizer, thereby increasing the crushing space of the crushing blade 8, thereby improving the crushing effect of the fertilizer. The bottom of the crushing box 2 is connected to a discharge shell 14, and a filter plate 10 is fixedly connected to the lower part of the inner cavity of the crushing box 2. Under the action of the filter plate 10, the crushed fertilizer inside the crushing box 2 can be filtered, so that the fertilizer with a suitable volume falls into the inside of the discharge shell 14, while the larger volume continues to stay in the crushing The interior of the box 2 is crushed by the crushing blade 8 to improve the fertilization efficiency of the device. One end of the stirring rod 7 penetrates to the other side of the filter plate 10 and is movably connected to the inner wall of the penetration point. The diameter of the stirring rod 7 is smaller than the inner diameter of the discharge port at the bottom of the inner cavity of the discharge shell 14. The stirring rod 7 is used in conjunction with the discharge shell 14. Under this action, the moving mechanism 9 can drive the crushing blade 8 to move through the stirring rod 7. The stirring rod 7 can clear the discharge port of the discharge shell 14 to avoid the crushed fertilizer from being stuck at the discharge port of the discharge shell 14, which effectively improves the fertilization effect of the device. Positioning grooves 11 are provided on both sides below the surface of the stirring rod 7. The surface of the stirring rod 7 is slidably connected to the positioning shell 12. The surface of the positioning shell 12 is aligned with the positioning grooves 11. The inner wall of the filter plate 10 is slidably connected, and under this action, the stirring rod 7 can drive the positioning shell 12 to rotate when it rotates, but the stirring rod 7 will not drive the positioning shell 12 to move when it moves up and down. The surface of the positioning shell 12 is fixedly connected with a scraper 13, and the two sides of the scraper 13 are designed with an inclined structure. The bottom of the scraper 13 is slidably connected to the top of the filter plate 10. Under this action, when the positioning shell 12 drives the scraper 13 to rotate, the larger fertilizer on the top of the filter plate 10 can be moved, thereby avoiding the situation where the larger fertilizer always blocks the filter plate 10 and the crushed fertilizer cannot be discharged, effectively improving the fertilization effect of the device. A guide groove 15 is provided at the bottom of the inner cavity of the crushing box 2, and the inner wall of the guide groove 15 is slidably connected with a guide ring 16.The inner cavity of the guide ring 16 is fixedly connected to one end of the scraper 13, under which the scraper 13 can be guided when it rotates, so that it will not easily shift its position during rotation, so that the filter plate 10 and the scraper 13 can fit more closely, and under the cooperation of the guide groove 15 and the guide ring 16, the positioning shell 12 can also be limited by the cooperation of the scraper 13, so that it will not move with the stirring rod 7.

[0026] The linkage mechanism 6 includes a mounting shell 61, the top of which is fixedly connected to the bottom of the worm 5, a connecting tube 62 is slidably connected to the surface of the mounting shell 61, both sides of the inner cavity of the connecting tube 62 are fixedly connected with a positioning block 63, the surface of the positioning block 63 is slidably connected to the inner wall of the mounting shell 61, and the bottom of the connecting tube 62 is fixedly connected to the top of the stirring rod 7. Under this action, when the worm 5 drives the mounting shell 61 to rotate, the mounting shell 61 can also drive the connecting tube 62 to rotate through the cooperation of the positioning block 63, and under the cooperation of the positioning block 63, the connecting tube 62 can also slide on the surface of the mounting shell 61, so as to facilitate the adjustment of the position of the stirring rod 7 in cooperation with the moving mechanism 9, and the top of the connecting tube 62 is rotatably connected with a movable sleeve 64, which is used in cooperation with the moving mechanism 9. Under the cooperation of the movable sleeve 64, the connecting tube 62 can drive the stirring rod 7 to move up and down while rotating, thereby increasing the crushing space of the crushing blade 8, thereby improving the crushing efficiency of the device, and also clearing the opening of the discharge shell 14.

[0027] The moving mechanism 9 includes a worm gear 91, which is installed in the inner cavity of the support frame 3 through a support seat. One side of the worm gear 91 is meshed with the worm 5. Both sides of the worm gear 91 are fixedly connected with a disk 92. One side of the disk 92 is rotatably connected with a connecting rod 93. The center of the circle where the connecting rod 93 and the disk 92 rotate is interlaced with the center of the circle of the disk 92. The surface of the disk 92 is slidably connected with one side of the connecting rod 93. Under the action of this eccentric design, the connecting rod 93 can move when the disk 92 rotates. One side of the connecting rod 93 is rotatably connected with a swing frame 94. One end of the swing frame 94 is connected to the support frame 3. The inner walls are hinged to each other, and under this action, the connecting rod 93 can drive the swing frame 94 to swing when it moves. The inner cavity of the swing frame 94 is slidably connected to the surface of the movable sleeve 64. The inner wall of the swing frame 94 in contact with the movable sleeve 64 is larger than the movable sleeve 64. Under this action, the movable sleeve 64 can move vertically when the swing frame 94 rotates, avoiding the situation that the movable sleeve 64 is stuck and cannot move due to the limitation of the mounting shell 61. The swing frame 94 can pull the movable sleeve 64 to move when it swings, thereby moving the crushing blade 8 up and down, thereby facilitating the crushing of the fertilizer.

[0028] It is worth noting that the technical features such as the storage mechanism 1 proposed in this technical solution should be regarded as the technology in the comparative case. The specific structure, working principle and possible control method and spatial layout method of these technical features can be selected according to the conventional methods in the field, and this technical solution will not be further elaborated.

[0029] Working principle: When working, first pour the fertilizer into the crushing box 2, then turn on the stepper motor 4. Under the action of the stepper motor 4, the worm 5 and the mounting shell 61 cooperate to drive the connecting pipe 62 to rotate through the positioning block 63, so that the connecting pipe 62 can drive the crushing blade 8 to rotate through the stirring rod 7, so as to crush the fertilizer inside the crushing box 2. Under the action of the worm 5, the worm wheel 91 is also driven to rotate, and the cooperation between the disc 92 and the connecting rod 93 causes the movable sleeve 64 to push the movable sleeve 64 to move. The movable sleeve 64 can move up and down through the cooperation of the connecting pipe 62 to drive the stirring rod 7 and the crushing blade 8 on its surface to increase the crushing effect of the fertilizer. When the stirring rod 7 rotates, the scraper 13 can be driven to rotate through the cooperation of the positioning shell 12 to clean the fertilizer on the surface of the filter plate 10 and increase the filtering effect of the filter plate 10. With the cooperation of the positioning groove 11, the stirring rod 7 can also move up and down to clear the discharge port of the discharge shell 14 to avoid the situation where the fertilizer blocks the discharge port of the discharge shell 14.
